A measurement of the number of magnetic field lines passing through a particular area or surface.
The voltage induced is directly proportionoal to the number of loops and the change in the magnetic flux. It is inversely proportional to the time that this change occurs throughout.
The induced emf always gives rise to a current whose magnetic flux opposed the original change in magnetic flux. Thus, the induced current tries to maintain the level of magnetic flux.
A voltage that gives rise to a current flow. This voltage can be induced or created by a changing magnetic field.
Right hand rule, RHR:
The fingers extend or curl in the direction of the magnetic field. The outstretched thumb points in the direction of conventional current.
A machine that produces electricity by a rotating coil of wire immersed in a stationary magnetic field. This rotating motion could be obtained from a variety of sources.
The situation where a changing current in coil creates an induced emf
The situation where the changing current in one coil creates an induced emf in another coil even though they are not physically touching at all
